PRX‑T33 Peel
in Dubai

Trichloroacetic acid, moderated

Trichloroacetic acid (TCA) is the standard agent for medium-depth peels. On its own it coagulates protein in the skin it touches; the whitening you see during a classic peel, called frosting, is that coagulation, and the skin then sheds over one to two weeks. PRX-T33 pairs 33% TCA with hydrogen peroxide. The peroxide reacts with the acid at the surface and blunts its caustic effect on the epidermis, so the solution passes into the dermis and triggers fibroblast activity there without destroying the surface. Kojic acid, a pigment-inhibiting ingredient, is added for tone. The result is a product that is massaged in rather than painted on and timed, with no frosting endpoint and no sheet peeling.

What the evidence shows

The published clinical evidence is a 2022 pilot in the Journal of Clinical and Aesthetic Dermatology: five women aged 49 to 72 with Fitzpatrick skin types II and III had four weekly PRX-T33 sessions with home care and were followed for 51 days. Investigator scores for tone, smoothness, texture, redness and overall appearance improved significantly, every participant improved in smoothness, texture and redness by the third visit, and no adverse events were recorded. The authors note the small sample and short follow-up as limitations. The manufacturer reports wide clinical use since the product’s launch. We treat this as promising evidence for skin quality, not proof of a specific percentage result for you.

Face, neck, décolletage and hands

On the face, PRX-T33 is used for dullness, early fine lines, rough texture, mild loss of firmness and uneven tone, including in younger and sensitive skin, which the manufacturer lists as suitable. The neck, décolletage and backs of the hands are treated with the same technique and are common add-ons, because these areas show sun damage early and tolerate classic peels poorly.

Body areas and stretch marks

The body service treats one area per vial: inner arms, abdomen, thighs, buttocks or knees, including skin with stretch marks or mild laxity after weight change or pregnancy. Body skin is thicker and renews more slowly, so we plan more sessions than for the face and judge change on photographs at review. PRX-T33 does not remove mature stretch marks; it can soften texture and improve tone around them.

What PRX-T33 will not do

It does not replace fractional laser or microneedling for acne scars, IPL or a laser protocol for sun spots, an injectable for volume loss, or a classic medium-depth peel when the aim is to shed sun-damaged epidermis. A dermatologist consultation decides which of these applies before you commit to a course.

PRX-T33 or a classic medium-depth peel

A classic medium-depth peel uses TCA at 20 to 35%, sometimes layered over Jessner solution, and is judged by frosting. Swelling worsens for about 48 hours and the skin crusts and peels over 7 to 14 days; sun must be avoided completely until healed. In return it removes sun-damaged epidermis, fine lines and flat pigment more decisively than any no-downtime treatment, and it suits Fitzpatrick I to III best because darker skin has a higher risk of blotchy pigment and scarring. PRX-T33 uses the same acid at 33% but blocks its surface action, so it trades that resurfacing power for no visible peeling and a course of several sessions. Choose the classic peel for visible photodamage you are prepared to peel for, and PRX-T33 for skin quality with no downtime.

PRX-T33 or a superficial peel

Superficial peels with glycolic, salicylic or lactic acid, or Jessner solution, exfoliate the surface: redness, then fine scaling for three to seven days, repeated every two to five weeks. They are the right choice for congestion, comedonal acne and surface roughness. PRX-T33 acts below the surface rather than on it, which is why it does not treat blocked pores; a deep cleansing facial or HydraFacial handles those.

PRX-T33 or BioRePeel

BioRePeel is the other TCA-based, low-downtime peel we offer for face and body. Its formula, downtime and uses are described on its own page. The practical difference for you is the endpoint: PRX-T33 is chosen when the aim is firmness and glow with no flaking at all; a peel that exfoliates is chosen when surface texture is the target. We confirm which applies at the consultation.

PRX-T33 or an injectable skin booster

An injectable skin booster such as Restylane Skinboosters places hyaluronic acid into the dermis with a needle; its evidence and duration are on that page, and injection marks and bruising are part of its recovery. PRX-T33 is applied to the surface, needs no needle and suits people who want no marks, but its effect on hydration and firmness depends on the skin’s own response. Some patients alternate the two; we do not do both on the same day.

Combining PRX-T33 with other treatments

PRX-T33 is often used to prepare skin before a laser or microneedling course and to maintain results afterwards. We leave one to two weeks between PRX-T33 and any other peel, laser or microneedling, wait two weeks after injectables, and can add LED light after a session to calm redness. Tell us what else is booked so we can sequence it.

Before your first session

Bring your skincare product list so we can confirm what to pause and when to restart. Do not stop prescribed treatment without your prescriber’s advice.

• Stop scrubs, exfoliating acids, waxing and hair-removal creams on the area for five to seven days.
• Avoid sunburn and deliberate tanning for two weeks, and use SPF 30 to 50 daily; we do not treat sunburnt or freshly tanned skin.
• Tell us if you get cold sores: TCA can trigger an outbreak, and we may prescribe antiviral tablets to start the day before.
• Tell us about pregnancy or breastfeeding, keloid scars, eczema or psoriasis in the area, diabetes or immune conditions, allergies, and any peel, laser or injectable in the last two weeks.
• Arrive with clean skin or let us remove makeup.

On the day

The skin is cleansed and degreased, PRX-T33 is massaged in in several layers until absorbed, and we finish with moisturiser and sunscreen. The face takes about 30 minutes; body areas longer. Warmth and tingling fade within minutes, and redness usually settles the same day.

After each session

• Keep the skin moisturised and apply SPF 30 to 50 every morning; reapply outdoors.
• Avoid saunas, hot yoga, swimming and heavy exercise for 48 hours, and direct sun for the rest of the course.
• Do not scrub, and do not pick at any light flaking; it lifts on its own within a couple of days.
• Restart exfoliating acids only when we say so, usually a few days after the final session.
• Makeup can be applied the next day.

Course and review

Sessions are usually a week apart. We photograph your skin at the start and after the course, compare the two and decide together whether a maintenance session every few months is worthwhile. Maintenance is a fresh decision after review, not an automatic booking.

Our product and clinical process

Evolution Aesthetics Clinic holds DHA Polyclinic License 6000514. We use authentic WiQo PRX-T33 obtained through an authorized supplier, stored and applied according to the manufacturer’s instructions, and we are happy to show you the paperwork. Sessions are performed by our licensed team under doctor supervision; where your medicines, skin type or history need a medical decision, a doctor assesses you first. We explain the expected change, the risks, the alternatives and the total price before you consent, and you receive written aftercare.

Common effects

Warmth, tingling and pink skin during and shortly after application; mild dryness, tightness or fine flaking for a day or two; a temporary flush on sensitive skin. In the published pilot the only effects were transient tingling and mild redness.

Less common effects

PRX-T33 is still a 33% trichloroacetic acid product. Burning sensations, prolonged redness, small superficial burns and crusting can occur if the skin is thin, over-exfoliated or tanned, or if too much product is applied. Post-inflammatory dark patches are the main risk in darker skin tones and after sun exposure; pale patches and scarring are rare. A cold-sore outbreak can follow treatment around the mouth. Allergy to kojic acid or another ingredient is possible.

When to contact us

Contact us the same day if you develop blisters, crusting beyond fine flaking, spreading redness or swelling, severe pain, signs of infection, a cold-sore outbreak, or dark or pale patches after a session. Eye contact with the product needs immediate rinsing and medical assessment.

When we do not treat

We postpone or decline PRX-T33 when any of the following applies:

• Active skin infection, cold sores or open wounds in the treatment area.

• Pregnancy or breastfeeding.

• A history of abnormal scarring or keloids.

• Recent sunburn or a heavy tan, or inability to avoid sun during the course.

• An inflamed flare of eczema, psoriasis or dermatitis in the area.

• Allergy to trichloroacetic acid, kojic acid, hydrogen peroxide or any other ingredient; a salicylate allergy matters for other peels and is recorded too.

• Uncontrolled diabetes or a significant immune disorder.

• Recent use of exfoliating acids or scrubs: tell us what you used and when so we can assess whether to delay the session.

• A tendency to post-inflammatory hyperpigmentation without pre-treatment and strict sun protection; darker skin tones are assessed by a doctor first.

A licence and an authentic product are firm standards, but they do not remove the effects above.
